<h3 id="rationale">Rationale:</h3>
<p>Parameters to <code>export</code>, <code>declare</code>,
<code>local</code>, <code>typeset</code> and <code>readonly</code> may
not have spaces around the <code>=</code> or <code>+=</code> operator.
This is the same as for regular variable assignments:</p>
<pre><code>export var = value   # Invalid: spaces around =
export var =value    # Invalid: space before =
export var= value    # Invalid: space after =
export var=value     # Valid</code></pre>
<p>This is because each individual argument to these commands is
interpreted as a string in the format <code>name=value</code>. By adding
spaces, you are instead passing the three strings <code>var</code>,
<code>=</code>, <code>value</code>, none of which follow this
format.</p>
